My original post did not go through, so please accept my apologies if this is received in duplicate. Hi What works: I am currently running the newest stable version of ganglia (gmond/gmetad) on FC3. I have adhered to the default gmond.conf and gmetad.conf configurations, including using MC address 239.2.11.71 and port 8649. The only exception is that my cluster is defined as CLUSTER in all .conf files. 'gstat -a' from the master node (running gmetad) sees all FCx boxes and this is reflected on the ganglia webpage. Furthermore, 'tcpdump -i eth0 upd port 8649' from the master shows that I am exchanging udp packets with the other FC3 boxes.
What doesn't work: However, I am unable to see a red hat enterprise 3 box despite using the same .conf files . Tcp dump from this box (RHE3) shows that UDP packets are being sent, but from the master they are not received. Moreover, although I can telnet to RHE3 at port 8649 from any host, 'HOST NAME" information is not listed as is observed with other computers. This behavior persists even with iptables off. Lastly, the computers are all connected by the same switch, so issues of communicating via MC 239. vs 224. shouldn't be a problem. Thanks in advance! pete
